The article considers conditions for increasing passive safety of vehicles due to the use of temperature calculation in friction pairs of brake units taking into account their active heat dissipation. This temperature calculation allows designers at the design stage of new brake units to determine their optimal configuration, required frictional surface of the friction brakes, taking into account their thermal stability in conditions of increased friction dynamics, which, ultimately, ensures passive safety of transport.

The interrelation of thermal modes of brake units of transport vehicles on their reliability and durability depending on operational factors of transport is considered. It is assumed that all the kinetic energy of rotating and translationally moving masses in the brake nodes is converted into thermal energy. In this regard, a criterion is used that characterizes the thermal energy released in the brakes and the operational criterion of transport vehicles. Comparison of these criteria makes it possible to evaluate the performance and durability of brake components, as well as to outline ways of their structural perfection depending on heat dissipation.
